Sec. 406.033.  COMMON-LAW DEFENSES;  BURDEN OF PROOF.  (a)  In an action against an employer by or on behalf of an employee who is not covered by workers' compensation insurance obtained in the manner authorized by Section 406.003 to recover damages for personal injuries or death sustained by an employee in the course and scope of the employment, it is not a defense that:
(1)  the employee was guilty of contributory negligence;
(2)  the employee assumed the risk of injury or death; or
(3)  the injury or death was caused by the negligence of a fellow employee.
(b)  This section does not reinstate or otherwise affect the availability of defenses at common law, including the defenses described by Subsection (a).
(c)  The employer may defend the action on the ground that the injury was caused:
(1)  by an act of the employee intended to bring about the injury;  or
(2)  while the employee was in a state of intoxication.
(d)  In an action described by Subsection (a), the plaintiff must prove negligence of the employer or of an agent or servant of the employer acting within the general scope of the agent's or servant's employment.
(e)  A cause of action described in Subsection (a) may not be waived by an employee before the employee's injury or death.  Any agreement by an employee to waive a cause of action or any right described in Subsection (a) before the employee's injury or death is void and unenforceable.
(f)  A cause of action described by Subsection (a) may not be waived by an employee after the employee's injury unless:
(1)  the employee voluntarily enters into the waiver with knowledge of the waiver's effect;
(2)  the waiver is entered into not earlier than the 10th business day after the date of the initial report of injury;
(3)  the employee, before signing the waiver, has received a medical evaluation from a nonemergency care doctor; and
(4)  the waiver is in a writing under which the true intent of the parties is specifically stated in the document.
(g)  The waiver provisions required under Subsection (f) must be conspicuous and appear on the face of the agreement.  To be conspicuous, the waiver provisions must appear in a type larger than the type contained in the body of the agreement or in contrasting colors.
